Astrophysics

No. Matter gets torn apart as it approaches a black hole. The mass itself is a singularity, which has no volume. It is debatable whether or not this can een be considered matter.

An astrophysicist is a scientist who researches the principles of light, motion, and natural forces as they pertain to the universe at large. He or she engages in theoretical physics studies in an attempt to learn more about the underlying properties of the cosmos. Many astrophysicists specialize in studying a particular phenomenon or theory, such as black holes, the development and extinction of stars, relativity and motion, or the origin of the universe.

You will need to learn a great deal more of mathematics for this question to be answered.

Competing theories for difficult questions are the life blood of science. Often parts of both are correct.

As yet there is no definitive solution.

The sun is never straight overhead at either of these two locations, as their latitude is greater than 23.5 degrees north.

Austin, Texas, is about 30.25 degrees north, so the sun will be 30.25 - 23.50 = 6.75 degrees off directly overhead, or 83.25 degrees above the southern horizon at noon on the summer solstice.

New York is about 40.75 degrees north, so the sun will be 40.75 - 23.50 = 17.25 degrees off directly overhead, or 72.75 degrees above the southern horizon at noon on the summer solstice.

If one does the mathematics (which are *WAY* beyond the math level of even most scientists), one finds that string theory works only if one assumes the vibrations are aking place in eleven dimensions. Choose another assumption and the mathematics falls apart. Or, more exactly, the mathe eventually leads to falsehoods.

It is SOMETHING like this: if one assumes that there are ten dimensions in string theory, you end up with 1 = 0

Only if you assume that there are eleven dimensions does one get 1 = 1

Destroying an asteroid is a complex and challenging task that would require careful planning and precise execution. Several potential methods for asteroid deflection or destruction have been proposed, including using nuclear explosives, kinetic impactors, or gravitational tractors. The difficulty of destroying an asteroid would depend on its size, composition, and trajectory.

A photon is classed as a 'massless' particle. However as mass and energy are aspects of the same thing it has mass by virtue its energy content.

It is not a simple and easily explained subject. It is necessary to learn some rather difficult mathematics.

Black holes can swallow anything that comes within their gravitational pull, including light and other celestial objects like stars and planets. Once an object crosses the event horizon of a black hole, it is consumed and cannot escape.

The temperature of the gas in dark dust clouds is typically very low, around 10-20 Kelvin. This low temperature is important for molecule formation because it allows atoms to move slowly and come together to form molecules through chemical reactions. In higher temperature environments, atoms move too quickly to successfully bond and form molecules.

Cosmic rays do not significantly deplete the ozone layer. The primary factor responsible for ozone depletion is human-produced chemicals like chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the stratosphere. Cosmic rays can influence atmospheric chemistry but are not a major driver of ozone depletion.

The idea of a black hole was first enunciated by physicist John Michell in a letter published in 1783. Later, the term "black hole" was coined by physicist John Archibald Wheeler in 1967.

Barnard's Star is the closest single star to the Sun, located about 6 light-years away in the constellation of Ophiuchus. It is a red dwarf star with a relatively high proper motion, making it one of the fastest-moving stars in the sky. It also hosts a high-probability exoplanet candidate, Barnard's Star b, which was discovered in 2018.

The farthest distance a human has ever reached from Earth is to the Moon, which is approximately 238,900 miles (384,400 kilometers) away. This was achieved during the Apollo missions conducted by NASA in the late 1960s and early 1970s.

millions of black holes are in all of the galaxies, and in the center of all large galaxies is an enormous black hole that makes all the stars go around it. the power was a million times greater 350 years ago. this cycle will repeat over again.

Scientists have come to believe that there is very probably a supermassive black hole in the center of the Milky Way, and that there may be supermassive black holes at the centers of many galaxies.

A black hole is much stronger than the sun in terms of its gravitational pull. Black holes have a gravitational force so strong that not even light can escape from them, while the sun's gravity is much weaker in comparison.

The gravitational constant mentioned by Newton was measured at the end of the 18th century by Henry Cavendish (in the Cavendish experiment), using a torsion balance or pendulum designed by Mitchell which measured the force between suspended lead balls, which twisted (or applied torque) to a bar, the magnitude of which is proportional to the force applied. His intent was to detemine the specific gravity of the earth, but his notes indicate a value for G which differs by only about 1% from the value accepted today.

Cosmic numbers are rare mathematical constants that appear to be related to fundamental physical constants in the universe. They are believed to have important connections to the structure and behavior of the cosmos, although their significance is still not fully understood. Examples include values like the fine structure constant and the proton-to-electron mass ratio.

When a stellar remnant is over about 3 to 4 times the mass of the sun (see Tolman-Oppenheimer-Volkoff limit) it is estimated to have insufficient outward pressure to resist gravitational collapse into a black hole. Note that larger stars would often explode into a supernova or become a planetary nebula, losing most of their mass this way first - perhaps over 75 percent - and thus the original star's mass needed to have a remnant heavy enough to collapse in a black hole would be much heavier than 3 times solar mass.

A stellar black hole would be the remnant or end product of the normal sequence of evolution of a star; the word 'stellar,' which simply means "pertaining to a star," disambiguates the type of black hole from those that might have been created through other processes, for example, primordial black holes thought to have been created in the early universe, or highly energetic particle collisions, etc. A stellar black hole is thus a black hole created when a massive star has exhausted its fuel and collapsed under its own gravity overcoming all outward forces which might resist collapse.

Mercury has almost no atmosphere at all, being too small and too hot to retain one. Trace amounts of molecular oxygen are present in a tenuous exosphere, and of course oxygen is bound in molecules on its surface rock and icy regions.

White holes are theoretical objects that are the opposite of black holes, expelling matter instead of absorbing it. They are not considered to be dangerous like black holes, as they do not have the same gravitational pull or ability to trap objects with their intense gravitational force. White holes are not thought to exist in our universe.

The main components of the universe are matter (including atoms and particles), energy, and the fabric of spacetime. These elements interact and give rise to everything we observe in the universe, including galaxies, stars, planets, and living organisms. Additionally, dark matter and dark energy are believed to make up a significant portion of the universe, even though they cannot be directly observed.
